ELECTRICAL COOKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 628,695, dated July 11, 1899.

Application filed March 10, 1899. Serial No. 708,512. (No model.)

To a whom, it may concern:

Be it known that 1, JOHN B. CARY, of the city of Baltimore, in the Stateof Maryland, have in vented certain Improvements in Electrical CookingApparatus, of which the following is a specification.

In the description of the said apparatus which follows reference is madeto the accompanying drawings, forming a part hereof, and in which Figure1 is a top View or plan of the apparatus with a part of the casingthereof broken away to show the interior. Fig. 2 is a partlysectionalfront view. Fig. 3 is a partly-sectional side View. Fig. at is apartly-sectional side view of a part of the apparatus.

Referring now to the drawings, A is the casing of the apparatus,constructed, preferably, of sheet-iron and adapted to stand on a table,a part of the top of which is shown in Figs. 2 and 3. WVithin thiscasing are vertical cylinders B, containing each, say, four incandescentlamps O. In order that the heat from the said lamps may be fullyutilized and. not wasted by radiation, the walls of the cylinders B aremade heat-retaining orno11-conductors of heat. If the cylinders areformed of sheet-iron, the wall is made double and the intervening spaceI) filled with some non-heatconducting substance, such as asbestos. Thesame eifect would be produced, however, by forming the said cylinders ofporcelain or earthenware or some other material having heat-retainingand non-conducting properties.

The cylinders are supported by legs 0 from the bottom cl of the casingA.

The electric lamps O in the cylinders are seated on and secured tonon-electricity conducting-rings D, fastened within the cylinders, asshown in Fig. 3. These rings may be made of porcelain.

The cylinders B are each provided with an inner cylinder fof sheetmetal, which is heatconducting, and with a sheet-metal plate E, whichserves as a cover for the cylinder and a support for a saucepan or othercooking vessel. Heat radiated from the lamps passes directly to thecovering-plates E and indirectly to them through the medium of the innormetallic cylinders f, to which they are united. Consequently nearly allthe heat de veloped by the lamps is utilized.

The plates E,with their cylinders f, are made removable for the purposeof renewing the lamps when they become inoperative from long use and forcleaning purposes.

F and G are the main electric wires, which pass down the verticalconduit H to the box I at the side of the apparatus, and pass thence tothe second box K at the front, where they connect with the branch wires9 and h, leading to the lamps. The front wall of the box K contains theswitches j and is provided with hinged doors or lids 7t, which giveaccess to the wires.

I claim as my invention- 1. In an electrical cooking apparatus, the

combination of a casing, a series of heat-retaining cylinders within thecasing, electric lamps within the said cylinders in an electric circuit,and heat-conducting plates situated on the cylinders upon which cookingvessels may be placed, substantially as specified.

2. In an electrical cooking apparatus, the combination of a casing, aseries of heat-retaining cylinders within the casing,l1eat-conductingcylinders within the heat-retaining cylinders and heat-conductin gplates secured to the said inner cylinders adapted to support cookingutensils, substantially as specilied.
